Abstract: The drawing textures of aluminum, copper, gold, silver, and Cu-7.3% Al bronze wires are approximated by major <111>+minor <100>, except silver wire, which can have the <100> texture at extremely high reductions. The <111> component in the drawing textures of aluminum, copper, gold, and silver transform to the <100> component after recrystallization. On the other hand, the <111> deformation texture of the Cu-7.3% Al bronze wire, which has very low stackingfault- energy, remains unchanged after recrystallization. The <100> + <111> recrystallization textures change to the <111> texture after abnormal grain growth. The Brass component {110}<112> in rolling textures of high stacking-fault-energy metals such as aluminum, copper, Cu- 16% Mn, and Cu-1% P changes to the Goss orientation {110}<001> after recrystallization. However, the Brass orientation in rolling textures of low stacking-fault-energy fcc metals such as brass and silver appears to change to an orientation approximated by the {236}<385> orientation after annealing. The texture changes are discussed based on the strain-energy-release-maximization model for medium to high stacking-fault-energy metals and on grain growth for low stacking-fault energy metals.

Abstract: It is well known that the deformation and recrystallisation of metals and alloys are accompanied by changes in texture and microstructure. These changes can lead to anisotropy in metal flow and affect the formability of sheet metals. Therefore, a significant amount of research on the development of textures and the principles governing them has been conducted in recent years. One of the most important factors contributing to the texture development of materials is the initial grain size. Unlike other factors such as stacking fault energy, strain and deformation temperature, relatively little work has been carried out on the effect of grain size on texture development, even though a considerable understanding exists regarding the effect of grain size on work hardening and recrystallisation kinetics upon annealing. Hence, this research describes the effect of the initial hot band grain size on the development of texture during cold rolling and subsequent annealing.
